Just map your gamma waves with the Muse headband as explained by Cody Rall MD:

And is Cody Rall not als a person who is but „psychologically noticeable“? As Peter Gamma from www.petergamma.org, who was labelled by the Swiss Police like that?:

Peter Gamma from www.petergamma.org is registered at the Swiss Police as a subject which is „psychologically noticeable“ – but Peter is not such a subject

But to be psychologically noticeable does not have to mean something negative. I can also mean that a person has extraordinary (gamma) brain waves.
